A Guide to Neurodiversity Celebration Week

What Is Neurodiversity Celebration Week?

Neurodiversity Celebration Week is an annual, global initiative that aims to transform perceptions of neurodivergence and celebrate the positives. Founded by Siena Castellon in 2018, Neurodiversity Celebration Week has a mission to work with schools, universities, and other organisations to change the narrative on neurodiversity in three areas: 

1. Increase acceptance and understanding
2. Provide education
3. Celebrate neurodiversity   

Research by Deloitte reveals neurodivergent individuals could make up around 17% of the workforce. But, due to low awareness and lack of self-identification, this figure may be underrepresentative of the true scale. In reality, many more people are likely to be unaware of their neurodivergence or hide it. To help these individuals acknowledge and appreciate their different ways of thinking, Neurodiversity Celebration Week offers a valuable opportunity for organisations to get behind their neurodivergent staff, increase education, acceptance, and celebrate the positives of neurodiversity at work. 

When Does It Take Place?

Neurodiversity Celebration Week is an annual event that happens across the globe. The next one takes place between the 17th to the 23rd March in 2026.

Support for Neurodiversity Celebration Week grows every year. Current reports suggest around 139 countries took part in 2024, including over 3,000 schools, 900 charities, and more than 7,000 other organisations. 

What Are the Benefits of Celebrating Neurodiversity Celebration Week at Work?

Promoting the benefits of neurodiversity can lead to many positive outcomes. For instance, studies show better neurodiversity in the workplace leads to 30% higher productivity. But also, more neurodiversity in teams results in greater creativity, innovation, and above-average results in quantum computing, machine learning, and data visualisation. 

Neurodiversity Celebration Week is a valuable opportunity to leverage these advantages and unlock the following benefits:      

• Showcases the value of neurodivergent talent: Every organisation has neurodivergent staff, even if they don’t know it. Neurodiversity Celebration Week offers staff permission to share their stories and highlight the advantages of being neurodivergent.  
• Raises awareness and education: Many people remain unaware of neurodivergence. While this is changing, neurodivergent staff continue to operate in a neurotypical world, and over 60% of neurodivergent people admit to masking their differences at work. 
• Encourages better inclusion: Greater rates of inclusion lead to better outcomes for everyone, at every level. Senior teams who embrace neuroinclusion not only improve their decision-making and problem-solving but they role-model neurodivergent leadership too. 
• Challenges stigmas: Faced with judgement and a need to mask their problems, three-quarters of neurodivergent employees experience secondary mental health issues. Embracing Neurodiversity Celebration Week shows solidarity for neurodivergent staff and helps to break down societal prejudice.  
• Boosts employer branding: Promoting the advantages of neurodiverse teams through social media and PR campaigns can lead to improved employer branding. This may also appeal to Gen Z employees, many of whom want to work for inclusive employers.  
• Encourages better creativity and innovation: Neurodivergent individuals often have very strong creative skills along with an ability to see things that others may miss. This can lead to exciting new projects, campaigns, and market differentiation.  

How to Celebrate Neurodiversity Celebration Week in the Workplace

So what can you do, in your organisation, to celebrate Neurodiversity Celebration Week in 2026? We’ve created some key pointers to help inspire you. 

Launch a Neurodiversity at Work Handbook

Dedicating a week to raising awareness of neurodiversity is vital for effecting change. But there could be a risk that efforts fall away when staff move on to the next issue. One way to tackle this is by compiling a Neurodiversity at Work handbook, guide, or manual. Launching an internal resource demonstrates a long-term commitment to improving neuroinclusion. And your copy may include the following: 

• Case study examples that showcase your organisation’s success with neurodivergence. 
• Guidelines on how to manage neurodiversity and details on differences between acquired neurodiversity, mental health issues, and clinical neurodiversity such as dyslexia. 
• Practical examples of how neurotypical and neurodivergent staff can support each other at work, along with details of supportive measures like the government’s Access-to-Work scheme.
• Aims or goals an organisation will commit to for increasing neurodiversity over time. 

Introduce Training

The vast majority of people have little knowledge of neurodivergence, but this is changing. Diagnosis rates for adult ADHD have increased and younger people are getting earlier recognition of their thinking differences. That said, most workplaces aren’t ready to support neurodivergent team members or to create safe environments to disclose.

A good way to overcome this issue is to provide staff with training on neurodivergence. Several charities and agencies run effective training programmes that may be suitable and worth exploring.  

You can also host a lunch-and-learn to demonstrate assistive tools like Caption.Ed or TalkType. Showing how live captions or speech-to-text software works can both celebrate neurodiversity and equip colleagues with helpful resources.

Run Social Media Campaigns

Neurodiversity Celebration Week is an opportunity to boost your employer branding and send a positive message to the external world that you’re an inclusive employer. Social media is the perfect way to showcase your efforts but also highlight your knowledge and awareness. Use this opportunity to show the world your knowledge and be honest about what stage you’re at. 

Set Up an Employee Resource Group for Neurodivergence

Unless you already have one, setting up an Employee Resource Group (ERG) on neurodiversity will help staff have their say, share their voice, and effect change in their working environments. 

There are some very positive examples of successful ERGs too. German firm SAP, for instance, experienced a 90% retention rate for staff on the autistic spectrum after forming an Autism ERG. 

Design Supportive Policies

Every organisation should have strong neurodiversity policies to help guide managers and staff in handling neurodivergence. Use Neurodiversity Celebration Week to form your neurodiversity policies, if you haven’t yet done so. Such policies should include awareness of neurodiversity and the reasonable adjustments your firm will or has made to accommodate the needs of neurodivergent staff.
